A rapid-entry shoe includes an actuator arm, having a pivot point, and a closure system. Movement of the actuator arm from an uncollapsed position to a collapsed position opens the closure system and movement of the actuator arm from the collapsed position to the uncollapsed position closes the closure system, according to various embodiments.

Foot support systems (and articles of footwear including them) include a midfoot flex component, such as a bi-stable spring element, that moves the article of footwear/sole structure/foot support component/midfoot flex component between an open position/foot insertion or removal configuration and a closed position/foot supporting configuration and vice versa.

An article of footwear includes a sole structure having a chassis and a bladder. The chassis includes a cavity and a plurality of pillars extending into the cavity. The bladder is disposed within the cavity and includes one or more chambers. Each of one or more chambers is supported by at least one of the pillars. The chassis may include a first plurality of the pillars extending from a first side of the cavity and a second plurality of the pillars extending towards the first plurality of the pillars from a second side of the cavity, whereby the bladder is supported between the first plurality of the pillars and the second plurality of the pillars. The one or more chambers of the bladder includes an interior chamber and a peripheral chamber at least partially surrounding the interior chamber and the peripheral chamber has a different pressure than the interior chamber.

Proposed is a technology which relates to a device for posture correction and Kegel exercises and is employed in a pair of foot-protecting means provided on the left and right feet to enable posture correction and Kegel exercises during walking without significant expense of time and cost. The device includes an upper plate, a lower plate, and a spiral compression part provided between the upper plate and the lower plate, wherein the upper plate rotates relative to the lower plate during vertical compression of the spiral compression part, the spiral compression part is coupled to the foot-protecting means of each of the left and right sides, and rotation directions of the spiral compression parts of the left and right sides are opposite to each other.

A shoe includes: a sole made of an elastic material and including a planta support configured to support a plantar surface of a foot; an upper attached to the sole and configured to cover the foot; and a heel counter provided above the planta support, arranged in a heel area of the upper, and covering a region of the foot from a medial side portion to a lateral side portion. The heel counter includes, in a lower rear portion of the heel area, a notch (deformation allowance portion) which is configured to allow impact deformation caused by upward movement of a rear portion of the planta support when the sole receives impact.

In one aspect of the disclosure, a knitted component may have a medial part, a lateral part, a forefoot region, a midfoot region, and a rearfoot region. The rearfoot region may include a first zone having a first level of stretch and extending from a lower region of one of the medial part and the lateral part toward an upper heel region. The first zone may have an elongate portion. The knitted component may include a second zone adjacent the first zone and having a second level of stretch greater than the first level of stretch. The second zone may extend into the medial part and the lateral part and may substantially cover a calcaneus region.
